Chemistry Balancing Equations

posted by .

I really need help with balancing these equations: PLEASE HELP!!

1. Sodium Hydrogen Sulfite reacts with hydrochloric acid to produce sulfur dioxide gas, water and sodium chloride

2. Sodium nitrate reacts with hydrochloric acid to produce nitrogen monoxide gas, water sodium chloride, and sodium nitrate

3. Nitro monoxide gas from the above reaction reacts with oxygen gas in the air to produce nitrogen dioxide gas.

4. Sodium hydrogen carbonate reacts with hydrochloric acid to produce carbon dioxide gas, water and sodium chloride

5. Hydrogen peroxide reacts with the permanganate ion and hydrogen iron to produce oxygen gas, manganese (II)ion, and water

6. Chlorine gas, water and sodium chloride are produced when hydrochloric acid is added to sodium hydrochloride, NAOCl

7. Sodium hydroxide reacts with ammonium chloride to produce ammonia gas, water and sodium chloride.


PLEASE HELP ME...I know how to balance them once they are written in a chemical equation
